Programming Glossary
This is our programming unit glossary!
- Argument
- An actual value (variable, constanat or declaration constant0 of a specified datatype provided when a sudprogram is called (into action); an argument lists as an ordered set of such values.
- Assignment Operator (:=)
- An operator which instructs the computer to store the value on its right side in the variableor declared constant whose name appears on its left side; pronounced "is assigned the value..' or "gets".
- Comma(,)
- symbol used to separate items in a list; good programming technique requires a blanck space after each comma.
- Comment
- text written for the benefit of the programmers; this text is never seem by the users of the programs.
- Concatenation(+)
- a binary string operator whose result is the concatenation (linking together) of the operands .
- Constant
- A value which never changes.
- Declared Constant
- A special kind of varable whose value cannot be changed once initialized(set).
- Dot-Dot
- option of the put keyword; instructs computer not to move te cursor to the beginning of the next line.
- Function
- A subprogram which returns value.
- Ouput Field
- the horizontal space taken by data put out by the computer; if no field width is specifies, the computer provides an output field whose length is exactly equal to the length of the data; string data are left justified and numeric data are right justified within an output field.
- Ouput Field-width
- For character stringsand integers, a single value is specified for the field width; for reals, two values can be specified: the overall width; 0 is a special value which specifies a field width exactly equal to the actual width of data (the defaylt width).
- Parameter
- A variable of a specified datatype required for the correct execution of a subprogram, a parameter lists specifies the order and dadtatypes of the values which must provide when a sudprogram is called (into action).
- Percent Sign(%)
- symbol used to mark the begining of a comment; the comment ends with t he line (there is no end comment symbol); % comment goes here is equivalent to < !--comment goes here-- > in HTML and /*commment goes here*/ in CSS.
- Procedure
- A subprogram which performs a defined task.
- Put
- keyword short for output; instructs computer to output objects to the run window, once the objects are output then cursor moves to the begining of the next line.
- Skip
- keyword used as object of put, instructs the computer to move the cursor to the begining of the next line.
- Subprograms
- A named program fragment.
- Sequence
- Unless a program specifies otherwise, the computer will execute each instruction of a program control in sequence, and all programs have at least one section of code which executes in sequence.
- Variable
- a named location in memory (RAM) sutable for the storage of data of a specific type: the value stored in their location can be changed, hence it's varaivle.
